Yazzy Simulator lets you create fake screens of conversations (or post and other screen) to share and have fun with friends.
Yazzy is an app available on the Play Store for about two years and has about 900,000 downloads.
Now it will be accompanied by Yazzy Simulator that, unlike Yazzy, does not just create static images of the conversations but creates real screens that simulate the real app, so it can fit to any device. Once created the conversation you can just make a screenshot and share it with friends.
At the moment you can create conversations WhatsApp, Facebook posts and photos, instagram post, twitter, google translator screens and system notifications. Other features will be added in later versions.
